Title: Improvements in or relating to benzene hexachloride and process for producing same
IPC: C07C17/02
Filed: 1952-02-14
Abstract: Benzene hexachloride is prepared by reacting benzene and chlorine in a cyclic process at a temperature of less than about 70 DEG  C. in actinic light by circulating a stream of benzene hexachloride in benzene solution between an absorption zone where chlorine dissolves in the mixture without reacting completely and a reaction zone illuminated by actinic light, a minor portion of the stream coming from the reaction zone is withdrawn for recovery of benzene hexachloride product and make-up benzene is added to the stream circulating to the absorption zone, chlorine being added in the absorption zone in an amount sufficient to maintain 17-22 per cent of benzene hexachloride in the stream leaving the reaction zone. Preferably the stream circulating to the absorption zone is cooled and chlorine is added in the liquid form.  Benzene hexachloride may be separated from unreacted benzene in the recovery zone by distillation and the benzene separated may be returned to the reaction as make-up benzene.  An example is given.

Title: Method of and Apparatus for Manufacturing a Concentric Neutral Conductor
IPC: H01B9/02
Filed: 1968-01-26
Abstract: 1,177,455. Corrugating; making electrical cables. KABEL - UND METALLWERKE GUTEHOFFNUNGSHUTTE A.G. 26 Jan., 1968 [28 Jan., 1967], No. 4252/68. Headings B3A and B3E. A method of making a neutral conductor consisting of corrugated wires disposed concentrically on a cable core, comprises uniformly distributing the individual wires on a circle concentric to the core, advancing the core axially and advancing the wires therewith, corrugating the wires one after the other by deflecting them transversely with respect to the core axis in dependence on the speed of advance, applying the corrugated wires to the surface of the core side-by-side, in positions oriented longitudinally with respect to the core, and securing the corrugated wires by taping and/or a sheath. An apparatus for carrying out the method comprises a hollow nipple having a bore 4 through which the cable passes and a number of bores 3 in the wall of the nipple which emerge at a conical face 5 formed between the large rear end of the nipple and the smaller diameter front end 6. A roller 7 which has edges chamfered to the same angle as the conical face 5, is rotatably mounted in a bracket attached to a ring 9 having external teeth which mesh with a driving pinion 10. The wire leaving the bore 3 is engaged by the roller 7 and two bends are formed in the wire. The rate of movement of the wire is related to the speed of rotation of the ring 9 so that during one revolution of the ring the wire advances by a distance c which equals a+b where a is the distance from a collar 8 to the junction of the smaller diameter 6 with the conical face, and b is the distance from this junction to the bores 3. In order to avoid the necessity for changing the nipple when the amplitude or pitch of the corrugation is to be changed, a collar 8 is mounted on the part 6, the diameter of the collar and its position along the axis being varied to adjust the amplitude and pitch. The ring 9 is movable axially to space the wheel 7 away from the face 5 by the wire thickness.

Title: Improvements relating to three-speed double change gear with a synchronising device
IPC: F16D23/06
Filed: 1937-02-15
Abstract: 495,857. Variable - speed gearing ; clutches. HERING, E. Feb. 15, 1937, No. 4568. Void. Convention date, Feb. 15, 1936. [Class 80 (ii)] Relates to gears wherein the engine may be clutched to one or the other of two coaxial shafts. The gearing itself admits of three speed-changes and thus, by using the shafts alternatively, six speeds and a reverse may be obtained. Synchronizing means are employed to facilitate changes. The inner shaft 8, Fig. 1, which has one end 8b journalled in the driven shaft 8a, is surrounded by a shaft 12. To a lay-shaft 13 is keyed a wheel 78 gearing with a wheel 81 keyed to the shaft 8. Freely rotatable on shaft 13 is a wheel 79 gearing with a wheel 80 fixed on the shaft 12. Between the wheels 78, 79 is a free-wheel clutch 84. On the shaft 8 is mounted one member of a clutch 87 serving to connect the driving and driven shafts 8, 8a directly. At its front end the shaft 8a has splines 88, Fig. 4, to engage splines 89 on a slidable wheel 90, Figs. 1, 4. When wheel 90 is moved to the left, the splines 89 engage the dog clutch 87. The shaft 8a is reduced to form a shoulder 104, Fig. 4, against which bears a bush 105 freely rotatable on shaft 8a and having a coned end 106 on which rotates a correspondingly coned ring 107. At the outer end of ring 107 are fitted balls 108. In the shoulder 104 a recess for each ball is provided, this recess being longer than the diameter of the ball. Certain splines 89a, Fig. 6, are shorter than the others and are tapered at their ends. To the bush 105 is keyed a wheel 109 provided at its front end with a clutch member 110 adapted to engage the splines 89. When the wheel 90 is prevented from moving axially, the pressure exerted by the gear-changing lever is transmitted to the ring 107 which ultimately rotates the bush 105, and wheel 109. When synchronism is obtained the balls 108 under the action of the gearengaging pressure slide along the inclined surfaces of the ribs 89a into an intermediate space 108b located between these ribs. The wheel 109 gears with a wheel 111 keyed on shaft 13. Adjacent the wheel 111 is a slidably mounted wheel 112. On a separate shaft 113, Fig. 2, is mounted a double wheel 114 for reverse. The wheels are moved by three forks 122-124, Figs. 2, 3. The gear lever may engage a recess 118, Fig. 3, in a plate 103 pivoted at 115 to move forks 122 or 123. When pushed downward it engages a recess in the fork 124 and is free of the plate 103. For first and second speeds, wheel 112 is moved to gear with wheel 90. For third and fourth speeds, the splines 89 and 110 are engaged. For fifth and sixth speeds, the splines 89 are engaged with the clutch 87.

Abstract: 879,118. Centrifugal separators. COHEN, K. P. Feb. 15, 1946 [Jan. 31, 1945], No. 4901/46. Class 23 A fluid mixture is separated into heavy and light components by continuously passing a first stream of the fluid in an axial direction through the central portion of a separator rotor, continuously passing a second stream of the fluid through the peripheral portion of the rotor in counter-current to the first stream, and rotating the rotor to concentrate the light component in the first stream and the heavy component in the second stream. The centrifugal separator shown in Figs. 1 and 2 is suitable for separating gaseous isotopes, and comprises an evacuated housing 178 containing a rotor 10 driven by a motor 22. The first stream is supplied to the bottom of the rotor by a pipe 40, a bore 18 in the rotor shaft, and ducts 42 whilst the second stream is supplied to the top of the rotor by a pipe 36, an annular passage surrounding a bore 14 in the rotor shaft, and ducts 38. The first stream leaves the top of the rotor through ducts 44 to the bore 14 from whence it is pumped by a centrifugal pump to the outlet 46, whilst the second stream leaves the bottom of the rotor through duct 38 to an annulus surrounding the bore 18 to be pumped by a centrifugal pump (not shown) to the outlet 38. The rotor shaft has damping means 26, 30, and is supported by a thrust bearing 34. The damping means 30 is similar to the means 26 which comprises a non-rotary sleeve 154 supported vertically by springs 172, spaced from the rotor shaft by a bearing 156, and carrying cylindrical vanes 160, 168 which respectively intermesh with stationary vanes 162, 170 immersed in oil. The position of the first stream may vary between 40%- 60% of the radius of the rotor. Where the first stream comprises a central cylindrical core it may have a radius of 75% of the rotor radius. About 4,000 of the separators may be arranged to separate isotopes from uranium hexafluoride and Fig. 8 shows a small section of the arrangement. Separators 184a .... 184d are connected to haeders 180, 200, 190, 194, and separators 206a, 206b are connected to the headers 190, 194 and to headers 210, 214 so that the gas in the header 210 contains a higher concentration of the light component than the gas in the header 190, and the gas in the header 200 is more nearly depleted of lighter component than the gas in the header 214.

[Class 64 (ii)] [See also Group XXIX] In a closed liquid-heating system in which the circulating liquid is maintained above atmospheric pressure and at a temperature above boiling point at atmospheric pressure, the flow of liquid through each of the consumers 4 arranged between flow and return mains 2, 3 is so controlled by a thermostat 6 as to reduce the flow when the temperature of the fluid leaving the consumer rises above a predetermined value, thus preventing more liquid than is necessary from flowing through consumers of low resistance or through consumers situated near the generator. The valves controlling the flow through the consumers may also be so operated as to reduce the flow automatically when the pressure in the circuit falls. Each valve may have a sliding sleeve seating which is set in accordance with the temperature of the contents of the consumer, the valve and its seating being operated by the pressure of a volatile liquid acting on bellows.
